**Use of taboo trigger word** You wake up your step-Mommy while she is in bed with your little step-sister. Wanting to fuck her, she tries telling you no as she doesn't want to wake your little step-sister or let her know that her big step-brother is fucking her step-Mommy. However, she's a bad fucking taboo step-Mommy, and she can't help but be naughty with her step-son. You get ontop of her, and she tells you to fuck her right there, right next to your little step-sister. She makes you call her a bad step-Mommy, knowing how wrong it is to do it without your step-sister knowing. She then wants a turn on top, watching as she rides you and watches your step-sister rest. She wants to be even worse for you, offering to spit on her face. When she does, she wakes, realizing that step-Mommy is fucking her big step-brother. She starts complaining, but your step-Mommy doesn't let her. She tells her she better sit there or get on the floor, that step-Mommy is a bad fucking taboo step-Mommy whether she likes it or not. Maybe your little step-sister can learn a thing or two...
